kernel (SL7)

* A stack buffer overflow flaw was found in the way the Bluetooth
subsystem of the Linux kernel processed pending L2CAP configuration
responses from a client. On systems with the stack protection feature
enabled in the kernel (CONFIG_CC_STACKPROTECTOR=y, which is enabled on all
architectures other than s390x and ppc64[le]), an unauthenticated attacker
able to initiate a connection to a system via Bluetooth could use this
flaw to crash the system. Due to the nature of the stack protection
feature, code execution cannot be fully ruled out, although we believe it
is unlikely. On systems without the stack protection feature (ppc64[le];
the Bluetooth modules are not built on s390x), an unauthenticated attacker
able to initiate a connection to a system via Bluetooth could use this
flaw to remotely execute arbitrary code on the system with ring 0 (kernel)
privileges. (CVE-2017-1000251, Important)
